Can a Bluesound Node 2i power supply really be upgraded?

I mean...by improving its components, not with a YOUR preferred streamer brand...;-)
Sure, you can upgrade the C-7 power cord. We all get that.

But, what about the power supply.
I only see 3 options:

1. Fidelity in UK
2. Some dude in Poland selling on eBay
3. Rumors of Teddy Pardo making one for the Node 2i.

It has to be DIY for the first two and not really what I'm looking to do with my streamer - I mean, if i'm going to to a DIY LPS upgrade, I'd like it to be easier to buy.

Anybody know anything or actually made it work?

So,  a little late on this input, but here it is.
I went to https://pd-cf.com/produkt/bluesound-node-2-2i-upgrade-low-noise-psu-interface/, which is the PD Creative website in Poland. I am an Aerospace engineer myself, so I asked a number of questions before buying the PS replacement. 
I ordered the upgrade kit without power supply and installed it in my personal Node 2i. I used a 5volt  Sbooster's BOTW LPS that I already owned to power it.
I have to say I was able to hear an immediate improvement in noise level and clarity.
This was a worthwhile investment for me. YMMV.

Agreed.  The Polish LPS upgrade makes it better.   Very good value for money.   Next is maybe a better DAC.

Installed the Polish upgrade in my Node 2i in less than 30 minutes.  Proof of the pudding?  My wife — not knowing I did this, asked me “did you buy something new? This is SO much clearer!  (She’s not an audiophile by any stretch of the definition).  In summary, I’m thrilled with the upgrade.   My 2c…

i posted this question to others on this thread, have not received any answers

for those who did the power supply upgrade on your node 2i, is the improvement you heard in the digital output clarity -- or is the improvement at the analog output?

in answering, please describe the rest of your system - dac (if applicable), amp, speakers in particular

thanks in advance

jjss49,
I use an external DAC and find both the PD Creative modified Node2i and new NODE tremendously improved. I’ve just added the Sbooster lps to the NODE and it’s a Significant upgrade as well. My system is listed near the end of a similar thread (see post 8-17-21) here: https://forum.audiogon.com/discussions/bluesound-node-2i-vs-upscale-streamers
Btw, as a stand alone streamer I find the NODE a notch or two above the 2i (Mean Well smps powering each).
